The Single State Registration System (SSRS), imposed on interstate regulated motor carriers, was repealed by Congress effective at the beginning of 2007.  In the future, the SSRS program will no longer exist.  

Instead, all motor carriers – regulated, exempt and private – as well as interstate brokers, freight forwarders and leasing companies are subject to fees under a new system.  The Unified Carrier Registration Agreement or UCRA, enacted by Congress and administered by states.  States will shortly begin to require interstate carriers and others to offer the UCRA program and to pay the new fees imposed under this program.
